Name of the Condition

  • Epididymitis

Summary

Epididymitis is the inflammation of the epididymis, a coiled tube at the back of the testicle that stores and carries sperm. This condition often causes pain and swelling in the scrotum and is commonly associated with infections. It can affect one or both testicles and may occur in males of any age, though it is most prevalent in those aged 14 to 35.

Causes

Epididymitis is frequently caused by bacterial infections, including sexually transmitted infections (e.g., chlamydia, gonorrhea) or urinary tract infections. Non-infectious causes, such as trauma to the scrotum, may also lead to inflammation. In some cases, the condition arises from viral infections (e.g., mumps) or as a complication of procedures involving the urinary tract.

Risk Factors

  • Being sexually active, particularly with multiple partners, increases the risk of sexually transmitted infections that can cause epididymitis.
  • A history of urinary tract infections or recent urinary tract surgery may elevate susceptibility.
  • Age (14–35 years) is a common risk factor due to higher rates of sexually transmitted infections in this group.
  • Lack of circumcision in males may also be associated with increased risk.

Symptoms

  • Pain and tenderness in the scrotum, often localized to one testicle.
  • Swelling of the epididymis or testicle.
  • Fever or chills.
  • Pain during urination or ejaculation.
  • Discharge from the penis (in cases of sexually transmitted infections).

Diagnosis

Diagnosis typically involves a physical examination to assess scrotal tenderness and swelling. Urine tests may be performed to detect infections, and a swab of penile discharge may be collected if a sexually transmitted infection is suspected. In some cases, an ultrasound of the scrotum is used to rule out other conditions, such as testicular torsion or abscesses.

Treatment Options

  • Antibiotics are prescribed for bacterial infections, with the choice of medication depending on the suspected cause.
  • Pain relief medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), may be recommended to reduce discomfort.
  • Scrotal elevation and cold compresses can help alleviate swelling and pain.
  • Sexual partners may need to be tested and treated if a sexually transmitted infection is identified.

Prognosis and Follow-Up

Most cases of epididymitis resolve with appropriate treatment within a few weeks. Follow-up care may include repeat urine tests to confirm infection clearance. If symptoms persist or worsen, further evaluation is necessary to rule out complications or alternative diagnoses.

Complications

  • Chronic epididymitis, which can cause persistent pain.
  • Abscess formation in the scrotum.
  • Infertility, though this is rare.
  • Spread of infection to the testicle (orchitis) or other parts of the reproductive system.

Lifestyle & Prevention

  • Practicing safe sex, including consistent condom use, reduces the risk of sexually transmitted infections.
  • Maintaining good hygiene and prompt treatment of urinary tract infections can help prevent epididymitis.
  • Avoiding activities that may cause scrotal trauma, such as contact sports without protective gear, may lower risk.

When to Seek Professional Help

Seek medical attention if you experience severe scrotal pain, fever, or difficulty urinating. Prompt care is important to prevent complications and ensure appropriate treatment.

Tips for Medical Coders

  • Use code N45.1 for epididymitis. Ensure documentation supports the diagnosis, including clinical findings (e.g., scrotal pain, swelling) and any identified causes (e.g., infection). If the condition is bilateral, additional coding may be required. Avoid using this code for non-inflammatory scrotal conditions or orchitis (inflammation of the testicle).
